Raspberry Pi OS • Re: Forcing HDMI Output

The Display is an iPad Mini 2/3 Replacement display with the old Abusemark DisplayPort breakout and the DP>HDMI Adapter is "BENFEI" of Amazon. I tried it with a different Adapter from Cable Matters, but the behavior was mostly the same. The display seems to turn on "eventually", which can be after 30 seconds, 30 minutes or 30 hours. It seems to me as if some timing needs to align, some timeout needs to occur or some other silly little flag just isn't tirggering right.

o.k. so we can clearly say your issue is related to the video signal chain.

Would recommend to get a suitable AD-Board from eBay/amazon which has a scaler chip doing the HDMI to DP-conversion. I'm using such boards i.e. with 13.3in eDP displays (from sub notebooks) . see an example below

There are no HDMI Capable boards for these old iPad screens available for purchase, unfortunately.
